Retief Goosen was quick to re-establish a dominant position at the top of the leaderboard during his third round at The Barclays Scottish Open.

The South African’s second round 63 at Loch Lomond had given him a two shot halfway advantage over Adam Scott, but before the twice US Open Championship winner took to the course, England’s Lee Westwood raced through the field with a round of 64.

The World Number 18, runner-up at the Open de France ALSTOM last week, could have gone even lower after nine birdies in his first 12 holes.

But the former European Number One was still pleased with his day’s work, especially as it came only two days after a chest infection hampered his progress during a two over par first round 73.

“I was thinking about 59 on the 13th tee,” said The Ryder Cup star. “I was really happy with the way I played today. All departments of my game feel good.”

Westwood’s round left him ten under for the week, only one behind Goosen’s halfway total.

But the South African added three birdies before the turn to race to 14 under and re-establish a two shot lead.

Gonzalo Fernandez-Castaño has moved into second, the British Masters champion from Madrid reaching five under for his round through 12 holes to go 12 under.

Wales’ Jamie Donaldson has climbed to 11 under after 15 holes – and has the added incentive of knowing that a top five finish may secure a spot at The Open Championship.

Also 11 under out on the course are Scott and his compatriot Marcus Fraser.
